Heterologous Expression of Recombinant Ginseng Tetradecapeptide in and Evaluation of Its Biological Activity.

Ginseng peptides, as bioactive components of ginseng, have attracted increasing attention. In this study, a 14-amino acid ginseng peptide was selected and heterologously expressed in using a multicopy tandem fusion strategy, named 7RS14α. The secondary structure of the recombinant ginseng tetradecapeptide (7RS14α) was analyzed, and a high-glucose model was established in mouse adipocytes to evaluate its biological activity. Transcriptomic profiling was further performed to elucidate its potential mechanisms. Results demonstrated that 7RS14α significantly enhanced glucose uptake in high-glucose model cells, likely by modulating lipid metabolism pathways and insulin signaling cascades, thereby influencing energy homeostasis in adipocytes.
